Steve Gilbert of is reporting that the Chicago White Sox are nearing a trade that would send closer Addison Reed to Arizona in exchange for third baseman Matt Davidson. (Update: The deal is now confirmed by both teams)

First, the fact that the White Sox would be sending away one of their better young assets in Reed is the biggest headline here. Reed saved 40 games for Chicago last season, posting a 3.79 ERA (3.17 FIP) in 71.1 innings of action, and generating 1.7 WAR (according to FanGraphs) as a relief pitcher. There is always the debate about just how “valuable” closers are in today’s baseball, but Reed was one of the better ones in terms of games finished last season, and at only 24 years old (25 by the start of 2014), he’s still quite young.
